2,3-DIMETHYLQUINOXALINE Usage And Synthesis

Chemical Properties

beige crystalline powder

Definition

ChEBI: A quinoxaline derivative in which the quinoxaline (1,4-naphthyridine) skeleton is substituted with a methyl group at each of positions C-2 and C-3.

Purification Methods

It has been purified by steam distillation with the base crystallising in the distillate. Recrystallise it from distilled water or aqueous EtOH. The sulfate crystallises from EtOH with m 151-152o(dec). [Gibson J Chem Soc 343 1927, Beilstein 23 H 191, 23 II 197, 23 III/IV 1277.]
